taramps ta2700

megael9 · 17th August 2011, 05:00 AM

I`m working with a taramps 2700. This unit has
the prot and the clip ligts sequencing on and off,
with a laps of about 1 sec in between. I checked
for shorts, and found nothing short.
Any idea?

If no one else can help, post a photo of the inside of the amp and I'll try to help.

PM fcruz (if he doesn't reply) to see if he has a schematic diagram or other information on it. This seems to be similar to the Stetsom amps which he seems to know fairly well.

not understand the defect or it turns on and off the LED lights and the protection of the clip

this amp from a defect in long line of the factory has a pre bulletin to replace all the TL072 a look at the transistors q1 and q2

I know I have to replace all the 072, But not sure if
I have to replace Q1, Q2, Q5, R125, R126 and the two
